+ * - As additional columns in the details view
+ * - As additional lines in the icons view
+ * - As menu entries in the "Sort By" and "Additional Information" groups
+ * - As popup menu entries in the details view header popup
+ * - As checkable entries in the View Properties dialog
+ *
+ * The AdditionalInfoAccessor provides a central place to get all available keys,
+ * the corresponding translations, action names, etc., so that modifications or
+ * extensions in KFileItemDelegate only require adjustments in the implementation
+ * of this class.
